John Goodenough’s Battery—and Work—Never Stopped Getting Better

A prototype solid-state battery based on lithium and glass faces controversy over claims that its capacity increases over time

Take the link.

“Technology” websites publish links about “new battery tech” every couple of weeks to cash in on the hype and to have an article to publish and profit off of.

There are dozens, hundreds of these articles every year and none of them have materialized into anything.

I will only care when batteries better than lithium ions are available for use in my devices.

That’s the team with Johnnie B. Goodenough. The man who invented the lithium-ion battery. The man who, at age 97, recently received a Nobel Prize.
No one else on the planet has more credibility in the field of rechargeable batteries than that man.
Helena Braga is the inventor of the glass powder electrolyte.
Over two years ago they stated that research on the electrolyte and anode was complete enough to begin work on commercialization, but the cathode still needed work.

Here is a thread I have been updating, detailing some press releases about the technology.

Goodenough still inventing at age 94. Glass battery.

Sunnysunsun: I object to your categorization of the nonprofit “Institute of Electrical and Electronics Engineers” as a “technology website”.

says it is still 3 years away

It is not really better until it is built and readily available

MtnDon:

For those that simply have their hands cupped, waiting for new tech to be delivered magically from the ether… sure.

For those that spend their lives devoted to electrochemistry - and especially the few as successful as Goodenough - ‘progress’ is defined differently. Consider what the path may have looked like to get us where we are. Be thankful.

Cheers

So Goodenough made a better battery?

SHIP IT already ! enough with the fawning and press releases…

A glass battery? The real question is whether the glass battery is half full or half empty.

Same here. I don’t care for hype, no matter the renown of the source.

To be honest, looking at the papers, research, and John B. GoodEnough’s and Maria’s background, this is 100% possible, and will be coming to market in the near future.

Glass electrolytes are mainly formed using lihtium salts, such as lithium hydroxide, lithium chloride, or if you wish for an inferior electrolyte, lithium carbonate actually(it is possible due to how the molecules are actually arranged in the glass electrolyte matrix).

They are then doped with barium to allow for much lower degradation during fast charging and super fast charging scenarios.

The main draw of this electrolyte is not as much as cost or safety, but rather, the ease of manufacturing.

Problems require smart solutions:

1. To lower cost and boost energy density at the same time, Tesla engineered aluminium canned 21700 cells. This allowed for slightly lower internal resistance, higher gravimetric energy density, and the use of a lower cost chemical formula while still retaining very high energy density.

2. Single crystal NCA/NMC electrodes. While this does decrease energy density a bit(less active material per surface are and volume), this allows for a huge increase in cycle life, due to the fact that larger crystals are easier to make with less imperfections, and are just more durable.

3. Glass electrolytes. This lowers internal resistance, costs, boosts cycle life, and allows for more efficient use of active material, along with possible use with exotic materials like silicon to boost capacity even further.

TLDR: Fun times are ahead. The future is now.

Now its only 2.5 years away, as the article was originally published in May.
